So long story - In July 2016 I purchased a second hand laptop which I sold via TradeMe at the end of January this year.

The purchaser has just this week filed a dispute with TradeMe that it has faulted.

Now normally with a private sale I would just say bad luck it's been 10 months. However in this case my TradeMe account is 'in trade'.

I didn't but the laptop to resell (as I used it for 7 months) and I don't sell laptops as a business on TradeMe - but as my account is 'in trade' I would imagine I have some responsibilities under the CGA? I don't have a second hand dealers license or anything like that.

So my question is - should the buyer want to take it further. How long is a reasonable time for a $500 second hand laptop to last? Am I being unreasonable saying 'bad luck' or would the tribunal not look favorably on that?

TLDR - How long would you expect a $500 second hand laptop to be covered by the CGA for?
